Title: Contaminated needle sterilizer
Inventor: GETTIG WILLIAM A
IPC: A61L2/04
Filed: 1992-05-19
Granted: 1997-05-13
Abstract: A sterilizing apparatus and method for contaminated  syringe needles includes an elongated heating tube having a central  bore capable  of receiving only the needle of a syringe  assembly  and which is heated by electrical resistance material surrounding the tube.  Precise regulation over the interval and level of  heating of  the  tube is provided through a power  controller  associated with logic circuitry, switches and a series of timers sequential-ly  initiated.  In this manner, should a fault in  the  apparatus exist  and the temperature within the heating tube not  reach  at least 482 degrees C. within the duration of the cycle of a  first one  of  the timers, the power controller interrupts  passage  of current  to the heating tube.  On the other hand, when this  tem-perature is achieved during the time cycle of the first timer,  a second timer is initiated and allows continued passage of current to  the  heating  tube for a prescribed  interval  calculated  to achieve  the  desired sterilization.  The concentrated  heat  as applied to the air within the restrictive tube bore  additionally physically  renders  the sterilized needle un-usable as  it  will have been annealed and this fact will be apparent from its black-ened appearance.

Title: A method of accessing a mobile radio land system from one of a number of mobile stations
Inventor: RAITH KRISTER
IPC: H04W56/00
Filed: 1992-07-31
Granted: 2002-04-09
Abstract: In a cellular mobile radiotelephone system, two different digital burst access methods are defined using to the greatest extent possible previously defined burst structures. The type of access method to be used in a particular cell is indicated on that cell's control channel. In very large cells, a two-burst access method is used including a shortened pre-access burst and a regular access burst. The shortened pre-access burst avoids collision with other bursts and provides time-alignment information to the cell's base station. In response to a time-alignment order, the mobile station then transmits a regular access burst. In smaller cells, a regular single-burst access procedure is used. The access methods use existing burst structures except that the fields CDVCC and SACCH are used for different purposes that may include improved synchronization, control channel identification and reservation of time slots for multi-burst access. Beyond a simple two-burst access method, according to a multi-burst access method, accesses may include essentially an arbitrary number of bursts limited only by system time-out limits.

Abstract: The preparation of a zinc mercaptoacid ester by the reaction of zinc oxide with the mercaptoacid ester in a wax matrix provides an  improved  heat  stabilizer  for  halogen-containing  polymer compositions.  The process obviates the necessity of isolating and transporting the normally very viscous zinc mercaptoacid esters. The zinc mercaptoacid ester/wax matrix is also an expedient medium for the preparation and utilization of calcium stearate as a lubricant in the heat stabilizer composition and the stabilized polymer composition containing it.  A paraffin wax is the preferred matrix for the preparation and use of the heat stabilizer and lubricant.

Abstract: An improved temperature control system using a state controller with two degrees  of  freedom to  regulate  the temperature of the barrel of an injection molding machine is disclosed.  The control system divides the temperature of the barrel  into  longitudinally-extending  zones  and  radially extending layers within each zone.  Heat transfer calculations which include the effects of heat transfer between all the layers within the zones are performed for a set time in the future to accurately determine the heat needed from the heater band to reach the operator set point temperature.  The duty cycle for the heater bands is thus accurately set to give a more responsive and accurate control than heretofore possible. The controller additionally includes factors for accounting for heat  disturbances  present  in  the  injection  molding process.   In addition each system is calibrated for each machine to insure accurate formulation of machine specific parameters such as heat transfer co-efficients used in the control.
